AKS/Journal/2010 Page 1 of 20 Aspects of Failure of Condenser tubes and their Remedial Measures at Power Plants Ashwini K. Sinha AGM (NETRA), NTPC Limited Abstract The demands placed on the condensers of utility generating units are significant. Functionally, a Condenser must condense several million pounds/kilograms per hour of wet steam at low temperatures while producing low absolute pressures. It must degasify condensate to the ppb level. These tasks must be done while also: Serving as an impervious barrier between steam/condensate and circulating water. Permitting only limited air inleakage. Contributing minimal corrosion products to the condensate in a hostile environment that is aerated, wet and at high velocity.
